Thank you for pointing this out. For now, I shall refrain from
upgrading, since this is a backwards incompatible change that affects
many files. Eventually, I'll make the required changes.

[NTG-context] Several math features broke for me in new Debian version

[Kumar Appaiah]

Dear Friends,

I am a regular user of ConTeXt. A recent upgrade of ConTeXt in Debian
broke things for me. The bug report is here:

https://bugs.debian.org/1055233

but I have reproduced the gist here:

Upon upgrading to ConTeXt 2023.05.05.20230730+dfsg-2, several math
features seem to break for me. Here is an example:

\starttext
Hello world!
\startformula
 X(f) = \startcases[align={right,left},distance=3pt]
   \NC T, \NC{} $|f| < \frac{1}{2T}$ \NR
   \NC 0, \NC{} $|f| \geq \frac{1}{2T}$ \NR
 \stopcases
\stopformula
\stoptext

The above works very well in 2021.03.05.20230120+dfsg-1+deb12u1 but
gives me this error in 2023.05.05.20230730+dfsg-2:

[NTG-context] Unable to switch math fonts

[Kumar Appaiah]

Hi.

I'm using the Debian packaged ConTeXt, version 2017.05.15.20170613-2.
I have the Neo Euler OTF font and mtxrun --script fonts finds it.

I am unable to get the following to work:

\definefontfamily [myfamily] [math] [Neo Euler]
\setupbodyfont[myfamily]

\starttext
This is plain text.
\startformula
x + y = z
\stopformula
\stoptext

The above code doesn't build for me with errors in the formula
portion. However, removing the Neo Euler line makes it work. Moreover,
this works:

\definefontfamily [myfamily] [serif] [Neo Euler]
\setupbodyfont[myfamily]
\starttext
This is plain text.
\startformula
x + y = z
\stopformula
\stoptext

But this makes everything, including math, Euler. Could you please help me out?

Thanks.

Thanks Aditya. Indeed, euler.otf was missing.

BTW, did I steal this slide style from you, by any chance? I couldn't
find out from a cursory search.

[NTG-context] \Umathquad\displaystyle not set

[Kumar Appaiah]

Dear ConTeXt users,

I have a custom slide template that I borrowed from another source
years ago. It works well on my Debian machine, but when I try to build
the PDF on a docker vm on Gitlab, I run into the
\Umathquad\displaystyle not set error. Surprisingly, that error
doesn't crop up on my machine.

Here is the complete (working) repository:

https://gitlab.com/kumanna/context-slides/tree/master

Here is the commit that causes the error online. Notice that I am adding the
{\bf \nabla} character:

https://gitlab.com/kumanna/context-slides/commit/b723c15dff6d7312605947f8bf46549cf1b22088

Here is the failed build log:

https://gitlab.com/kumanna/context-slides/builds/9972477

Is there something I am missing?

Thanks.

[NTG-context] Evaluating a Lua expression at the end (repeat)

[Kumar Appaiah]

Dear List,

Last year, Hans helped me with this example:


\starttext

\startluacode
 local name = nil
  local temp = 0

 function document.startwhatever(s)
   name = s
   temp = 0
end
 function document.addwhatever(n)
  temp = temp + n
   context(n)
end
 function
  document.stopwhatever()
   job.variables.save("document:temp:"..name,temp)
end
 function document.getwhatever(s)
  context(job.variables.collected["document:temp:"..s])
   end
   \stopluacode

\def\startwhatever[#1]{\ctxlua{document.startwhatever("#1")}}
\def\stopwhatever {\ctxlua{document.stopwhatever()}}
\def\addwhatever#1{\ctxlua{document.addwhatever(#1)}}
\def\getwhatever#1{\ctxlua{document.getwhatever("#1")}}

total: \getwhatever{foo}

\startwhatever[foo]

test 1: \addwhatever{10}\par
test 2: \addwhatever{20}\par
test 3: \addwhatever{30}\par

\stopwhatever

\stoptext

However, on my current ConTeXt on Debian (2016.05.17.20160523-1), I am
unable to get it working. It says:

[NTG-context] Evaluating a Lua expression at the end

[Kumar Appaiah]

Hi.

I am trying to set up a system where I can use Lua to find a total
that I can display at the end. For example, if I set a question paper,
after each question, I do a \directlua{total = total + 4}, assuming
this question has 4 points. At the top of my document, I now want to
say Total points: and display the value of total.

Now, naturally, using \directlua gives me 0, since total is 0 at the
beginning. But \latelua didn't seem to be what I am looking for. Could
someone please guide me in the right direction?

Thanks.

[NTG-context] Using Euler with simplefonts

[Kumar Appaiah]

Hi.

I am trying to use the simplefonts approach to get Euler for math,
along with TeX Gyre fonts for text. I've looked at some of the past
list archives and I haven't yet been able to figure this out.

I use TeXLive, and my context is 2014.05.21.20140528-1 (Debian
version). Here is the font blurb:

\definefontfamily [myfamily] [serif] [Linux Libertine O]
\definefontfamily [myfamily] [math] [Tex Gyre Schola Math]

Now, I have tried changing the TeX Gyre Schola Math to Neo Euler,
Euler and some other variants, but it doesn't work.

I do have the Euler VM fonts installed on my system. I have also tried
the example program given in http://www.ntg.nl/maps/32/06.pdf

\definetypeface[eulermath][mm][math][euler][euler][rscale=1]
\setupbodyfont [eulermath]
\starttext
\showmathcharacters
\stoptext

This works with texexec, but with context, it chokes.

Could you please provide me some pointers?

Thanks.

 Here is setup magic from Hans and Aditya from August 2013:

 One can change the families, e.g. schola for pagella, etc., but I think the  
 last [pagellaovereuler] and the rest has to stay.

Sadly, I get this:

 you can directly runt it with the context command.

[NTG-context] Quick slide templates

[Kumar Appaiah]

Dear ConTeXt list,

This could be more of a style and TeX question than a ConTeXt
question. Nevertheles:

I am making a presentation that involves some simple animations. The
way I make those animations is by:

1. Stopping page numbering.
2. Flipping through the same slide repeated, but with img0, img1, img2 etc.
3. Start page numbering.

The problem with my naïve approach of repeating slides is that fixing
a spelling error or making changes implies that I have to do it several
times for an “animated” slide, and is error-prone. Could you point me
to a way by which I can make a slide something like a “function” whose
argument is the image, and calling it creates that slide with an
image?

FWIW, I use texexec --xtx, but I am guessing a LuaTeX solution would
be simpler. The XeTeX solution is what I am not able to find now.

Thanks!

I got it. rulecolor is the option to setupfootnotes that did the

I'll try looking and the source code more often to figure out what
options are used for various commands, since the documentation doesn't
seem to cover all options.

[NTG-context] Bold math trouble

Hi.

I use ConTeXt in Debian. If this helps, please keep it in mind:

dpkg -l context gives:

Now, if you consider the following:

code
\usetypescript[palatino][texnansi]
\definetypeface[mainface][mm][math][modern][modern][encoding=texnansi]
\definetypeface [boldmath] [mm] [boldmath] [modern] [modern] [encoding=texnansi]
\switchtobodyfont[palatino,14pt]

\starttext
Hi
\startformula
x = \boldsymbol{\Sigma}\Sigma
\stopformula
\stoptext
/code

The issue I have is that this doesn't work, and throws me:

! Math formula deleted: Insufficient symbol fonts.
\mathboldsymbol ...t]$\mathsurround \zeropoint #1$
  }} {\hbox {\switchtoformul...
l.9 x = \boldsymbol{\Sigma}
   \Sigma

However, if I make the 14pt above 11pt or 12pt, it works perfectly. Is
there something I am doing wrong?

Thanks.

Copy paste it into the ConTeXt Live interface at the ConTeXt

 You have a problem with metapost not being run. Search the
 contextgarden for write18 for the solution.
 
 BTW: You cannot use the contextgarden to check if you code
 is working. The same restrictions as on your system apply.
 Consider using mkiv as Hans suggested.

Indeed, this was the solution. I added metafun to
shell_escape_commands, and that did the trick!

Thanks!

Dear Mojka,

On Sat, Sep 08, 2007 at 11:14:30AM +0200, Mojca Miklavec wrote:
 Since plain metapost doesn't know about ConTeXt (metafun) extentions,
 you need to:
 - either add a line input metafun ; at the top of your metapost files

This works just as I expect! Many thanks!

 - or run mptopdf seminar.mp which will run metapost+create PDF
 instead of running mpost/mp seminar.mp first and convert to PDF
 later

This gives me some font issues, but I am not really bothered, since
the excitement of seeing the first solution work has stopped me from
probing further here.

 When including a picture in ConTeXt, one options could also be to use:
 \framed[frame=off,offset=1cm,strut=no,background=color,backgroundcolor=white]%
 {\externalfigure[...]}
 But that's slightly long and tedious, unless you write your own macro
 wrapper around it.

I understand, but it will be useful elsewhere.

Again, many thanks!

OK, a cheap and dirty workaround: define a blank label at a location
outside the bounds of your actual picture, and MetaPost does the
needful. Inelegant, but works for now.

My next free-time-assignment is to learn MetaFun, since I've read
enough to know that by not knowing it, I'm missing something
significant.

Well, that seems to be a nice option, but it fills the offset region
in the background colour instead of white. I'll try to figure out if
there's some workaround for that. Also, I'll try Oliver's solution,
though it seems to generate full pages and not individual images.

But, is there still an elegant way to have more margin in MetaPost
images?

Thanks!

[NTG-context] Margins around figures

[Kumar Appaiah]

Deat ConTeXt users,

I am making a presentation with ConTeXt, with numerous MetaPost
figures. Now, the only problem is that my white MetaPost figures don't
blend well with the dark background of the screen. This isn't too good
since the text labels in my figure's edges appear too close to the
edge. What I'd like to know is, whether there's a way to specify some
extra margin space around the figure, which would provide some more
white area around the MetaPost figure. Alternately, is there an
elegant MetaPost way of specifying figure margins?

Oh, and my MetaPost files are in separate .mp files; I include them
after converting.

Thanks!

[NTG-context] Background colour of included PDF images

[Kumar Appaiah]

Dear ConTeXt users,

I am making a presentation using ConTeXt, and wish to use some plain
images. I am running into some trouble, especially with the background
colour of the image, which I wish to force. Here is some information:

1. I make the image using Dia, and export it.
2. I include the EPS directly, and Acrobat doesn't like it.
3. I epstopdf the images, they come otu well, except that they are
   transparent and the images with black text and lines looks bad on
   my dark background presentation.

I partially worked around the problem by using background=screen in my
\useexternalfigure calls. However, I have a combination image, where
the second image comes without the white filled background.

Could you please tell me a way to force the background colour of my
images to white? I really don't want to convert it to PNG or
something, since PNG doesn't look nice after scaling, does it? :-)

Thanks in advance.

And FYI:

Version: Debian package:
CtxTools | context version: 2007.04.17 12:51 
(/usr/share/texmf/tex/context/base/context.tex)
CtxTools | context version: 2007.04.17 12:51

[NTG-context] Chapters without page breaks

[Kumar Appaiah]

Dear ConTeXt users,

I was wondering whether there was a simply way to avoid a page break
after \chapter. It'd be nice, since I am writing a small report.

I did try \setupsectionblock, but didn't quite get it. Could you
please suggest the right way?

Thanks.

[NTG-context] Forcing pictures to stay in sections

[Kumar Appaiah]

Dear ConTeXt users,

I would like to do something like this:

I have a couple of sections in my page, and some graphics (fairly big,
each 1/4th of the page size, say) to be laid out in the sections. Now,
there are some sections in which one of the pictures is laid out on
one page with some text, but there isn't place to get the image on the
same page. So, the image is put on the next page. However, if I start
a new section, the image appears under the new section (that is, after
the new section heading), which I don't want. How do I enforce the
picture to be laid out before the next section heading?

One simple way to do it would be to force a new page before a section,
but I want to save that space! :-)

Thanks.

 a 60 page booklet from LaTeX to ConTeXt where is now successfully

 have no apparent effect:
 \setupbodyfont[palatino]

 Do I need to select some interface to the fonts like I

 Good thinking! But unfortunately, this won't work if you do it

 You have to give the same commandline as context's texexec does.
 Dvips does not support mapfile \specials, so unless you feed it
 the needed files on the commandline, it will read the wrong map
 file.
 
 The used commandline is included as a comment at the top of the
 generated postscript file, so the best approach is to do a run of
 texexec --dvi and then extract the commandline from the output
 (and insert the -d 127 , of course)

Done that. Now, it does seem that the map files are being looked
at. However, doing this results in a new PS file, where the fonts for
math look awful. The specimen is here:

http://www.ee.iitm.ac.in/~ee03b091/test.ps

And the dvips command extracted from the PS file is:

dvips -d 127 -u +texnansi-public-lm -u +original-base -u \
+ec-public-lm -u +ec-base -u +lm-ec -u +lm-math -u +8r-base -u \
+t5-base -u +original-ams-base -u +original-ams-euler -u \
original-public-lm test

And the dvips output is at the same place:
http://www.ee.iitm.ac.in/~ee03b091/dvips_output.bz2

Hope I'm getting somewhere. Thanks for the support!

Thanks for all the help, but one final question before I give up!

IF I use pdflatex, this is the header of a PS file I get upon doing
dvips:

%!PS-Adobe-2.0
%%Creator: dvips(k) 5.95b Copyright 2005 Radical Eye Software
%%Title: myfile.dvi
%%Pages: 1
%%PageOrder: Ascend
%%BoundingBox: 0 0 595 842
%%DocumentFonts: CMR17 CMR12 CMBX12 CMR10 CMMI12 CMEX10 CMSY8 CMMI8 CMR8
%%+ MSBM10 CMR7 CMBX10 

However, for ConTeXt, the output I get is:

%!PS-Adobe-2.0
%%Creator: dvips(k) 5.95b Copyright 2005 Radical Eye Software
%%Title: test.dvi
%%Pages: 1
%%PageOrder: Ascend
%%BoundingBox: 0 0 595 842
%%DocumentFonts: LMRoman12-Regular CMR12 LMMathItalic9-Italic
%%+ LMMathItalic12-Italic LMMathSymbols10-Italic

Now, is there any way to force the fonts to map on to the old CMR
names? That is because I feel it is because of the CMR/lmodern issue
that pdflatex generated PDFs appear properly, while ConTeXt ones
don't. What should the map file look like?

Also, please find the Debian default map file here:

http://www.ee.iitm.ac.in/~ee03b091/original-public-lm.map.gz

Thanks for bearing with me. I want to try my best before giving up,
failing which I will be forced to return to teTeX (with the old
ConTeXt) and miss out on some new ConTeXt niceties, such as
\startalign etc.

Thanks.

And one more observation. dvipdfmx converts the math fonts correctly,
and math symbols appear right. However, the font still doesn't look
the same in Acrobat, like that which I get if I use the old ConTeXt.

Haven't printed it, yet, but I think it would be a fair assumption
that printing would give a result as expected; i.e. it will print as

So, that means I shouldn't worry about the slightly bad rendering?
That is all right. But I am yet to figure out why dvips/divpdf fail
while dvipdfmx seems to get the math symbols right.

OK, so here's the diagnosis. The file you have quoted above is what I
used.

1. texexec test.tex: Gives a PDF which renders all symbols. However,
   the font display in Acrobat isn't perfect (it's a bit light), but
   should be perfect when printed.

2. texexec --dvi test.tex;dvips test.dvi;ps2pdf test.ps: Same result
   as the previous.

3. texexec --dvi test.tex;dvips -Ppdf test.dvi;ps2pdf test.ps: Oops!
   \cdot is missing

4. texexec --dvi test.tex;dvipdf test.dvi: Oops! \cdot is missing again!

If you still need test.log, I can upload it, but it doesn't have
anything strange. Also, as Taco had suggested regarding the map file,
I checked that original-public-lm.map has the entry for cmr10 etc.

Finally, hoping that I'm being smart, I have bzip2ed the output of
dvips -d 127 -Ppdf test.dvi. Please check the directories searched for
the map file; the directory in which original-public-lm resides is
/usr/share/texmf/fonts/map/pdftex/context and it doesn't appear on
that list, but I'd like you to confirm.

Get it at http://www.ee.iitm.ac.in/~ee03b091/dvips_output.bz2

Same holds for \Omega. Actually, there is something wrong with the
fonts; CMR fonts don't seem to be used. Here is an example:

See caption for figures 4, 5, 6 etc. These should have a \Omega
wherever there's a blank. Also move to the last page, the font
rendering for math is far from OK. I am, in general, unhappy with the

A similar document made with the old ConTeXt is:

The fonts render very well in Acrobat as well as have all
symbols. This is what I was mentioning.

Well, this is the switch to lmodern in all the fonts. Your
(ee03b091_nice.pdf) document has these fonts:
QGWSVP+CMR10 Type 1C  yes yes no  10  0
GLMABO+CMCSC10   Type 1C  yes yes no   8  0
KOSSLE+CMBX10Type 1C  yes yes no  12  0

while the new one ships:

Complain to ConTeXt about this switch, or ask them to support the cmr
fonts. This is probaly the only way to go.

So, what is the suggestion?

[NTG-context] Problems with fonts

[Kumar Appaiah]

Dear ConTeXt users,

I am a Debian GNU/Linux user. I recently upgraded from an old teTeX to the
latest ConTeXt in Debian. With the upgrade, however, I got a missing
cont-en.fmt error (http://bugs.debian.org/409575) which I solved by doing a
texexec --make --all, and placing the cont-en.fmt from my .texmf-config into
/var/lib/texmf/web2c and ran texhash. Things seem to be OK.

But now, whenever I do texexec filename, I get a PDF with many mathematical
symbols missing. So, I do this:

texexec --dvi ee03b091.tex
dvips ee03b091.dvi
ps2pdf ee03b091.ps

Now, this seems to work, but the fonts are not rendered as well as they used
to in Acrobat.

And this also does not give the fonts, but causes the same math trouble again:

texexec --dvi ee03b091.tex  
dvips -o ee03b091.ps -Ppdf ee03b091.dvi 
ps2pdf ee03b091.ps

What could be wrong? Is my installation broken? Can I salvage it?

Thanks.

I'll do the downgrade and get back to you. Thanks for the suggestion.

 I don't know where your problems come from.
 You could just try using the package from my site:

 Don't forget to texhash!
 

Thanks. I did the same, and I still have a similar problem. I
installed the font in /usr/local/share/texmf, and ran texhash. Now,
that ls-r has the font info. I am getting the following:

(Part of the output):
kpathsea: Running mktexmf ec-genr101

? H
I wasn't able to read the size data for this font,
so I will ignore the font specification.
[Wizards can fix TFM files using TFtoPL/PLtoTF.]
You might try inserting a different font spec;
e.g., type `I\fontsame font id=substitute font name'.

Could you give me any further suggestions?

Thanks.

 As you see, we have some problems with TrueType fonts.
 My font package from this morning is better than the old one, but  
 still lacks at least the 'dcroat' letter.
 
 But your problem is another kind.
 I'd suggest to start over and use the latest Gentium distribution  
 (1.02), but so far:

Now, that is what I am doing.

 What Gentium files do you have in your fonts tree? Which vendor/ 
 collection names did you use? (sil/gentium?)
 - AFMs (not needed)
 - TTFs (texmf/fonts/truetype/sil/gentium/*.ttf)
 - TFMs (texmf/fonts/tfm/sil/gentium/*.tfm)
 - MAPs (texmf/fonts/map/pdftex/context/ec-sil-gentium.map)

I have all the files, and again, I tried to do the wiki's
suggestions. Now, whenever I compile the test file, I get an error in
Acrobat saying Cannot find font in Resources, using Helvetica
instead.


 Did you rename all files to lowercase (and without spaces)? ConTeXt  
 sometimes has problems if file names use uppercase letters.

I have done this, and I believe that this helped.

 There should be ec-genr101.tfm and .ttf in your case, that's what TeX  
 is looking for.

Yes, I have the 102 ones.

 If the TFM is found, you'll run in the next problem: Probably in  
 the .map file there's '.pfb' instead of '.ttf'

No, that seems all right.

 I always need to run texhash with root permissions ('sudo texhash'),  
 otherwise the database cannot be written.

I also run it with root permission.

Thanks for your patient responses. If you think you can suggest
anything further, please do so; though I am on the verge of giving
up...

BTW, it might help if you know that I am using tetex-3.0 on Debian
GNU/Linux.

Thanks again.

[NTG-context] Problems installing Gentium TTF

[Kumar Appaiah]

Hello! I am tryingto install the Gentium True type fonts, following
the instructions at
http://wiki.contextgarden.net/Installing_a_TrueType_font%2C_step_by_step

Everything went of well, and I was also able to get the pages of
glyphs from the tests. However, when I try to get the test document
provided at the end of that page to work, I get:

bodyfont: unknown variant MyGentium

from texexec. I have installed the fonts with --en=ec, so that is
ruled out. What could the problem be?

Thanks.

[NTG-context] Reg. fonts and math

[Kumar Appaiah]

I have been using ConTeXt for a short time now, after I switched from
LaTeX. I find it quite great, but I have two queries regarding it. I
am using teTeX in Debian (unstable).

1. Are the Lucida Bright fonts used in the documentation part of the
   complete teTeX documentation or are they fonts which need to be
   obtained separately? I have read a thread about this on the archive
   of this list, and tried all possible combinations suggested there
   in vain.
2. The tutorial tells us to refer to other sources (The TeX Book) for
   more on Math typesetting. Is there any online resource which would
   explain TeX (as opposed to LaTeX) math?

Thanks.
